Been trying to get network manager working. I have the applet but when
I click on it it only shows wired network, and this is only if I start
eth0 manually. Currently I have eth0 and ra0 in my interfaces file
(neither with auto). I have also started er0 and it does not show up.

Network Manager doesn't play nice with /etc/network/interfaces :)
You need to comment out all interfaces in that file except for the "lo"
stanza which normally looks like

#loopback
auto lo
iface lo inet loopback

Recently I've seen a couple of notes on the Network-manager list that it
_should_ work as long as other interfaces have no options other
than "dhcp" - but that hasn't worked for me, so I'd stick to this really
simple version.

The applet I have had no drop down;(

Probably because your interfaces file is confusing Network Manager,
although I might be wrong...

Yes.

Things I discovered the hard way:

1) Make sure that your card supports/ will work with wpasupplicant if you
are using the latest Network Manager and nm-applet packages

Yes. wpasupplicant has been a real bugbear for me.

2) You can sometimes persuade N-M to behave by running

sudo /etc/init.d/dbus restart

And if you change anything (like removing your interface
from /etc/network/interfaces) you _must_ restart the NM daemon by
restarting dbus.

then starting nm-applet

Shouldn't have to restart nm-applet (I use knetworkmanager which certainly
picks up any new settings once dbus is restarted).

4) If N-M has one of its periodic attacks of amnesia, sometimes clicking
the drop down ( left click on applet) and selecting the alternative
interface will convince it to remember that wireless is present ( or
wired, if that is connected)

I haven't seen this problem.

5) There's a fair bit of useful stuff on

https://help.ubuntu.com/community/WifiDocs/NetworkManager

6) Try to keep a sense of humour. Network Manager seems to be very much a
work in progress ;-)

It is. It's _mostly_ ready for primetime - now that my wireless interface
seems to be working again, I'll be using it fulltime, but for a month it's
been flaky.

When it works, it's very nice. It's a bit temperamental at times, it
seems...

Agreed. btw, the whole /etc/network/interfaces business is apparently
something debian or ubuntu introduced. The vanilla upstream NM doesn't
care, but somebody wanted a way to force NM to ignore certain interfaces.
